Primary sources: NVD · CVE.org · FIRST EPSS
Databasement before 1.10.9 contains an authentication bypass vulnerability in OAuthService::findOrCreateLocalUser() that links OIDC identities to local users by email without checking email_verified. Attackers can register an identity provider account with a victim's unverified email to log in as any user, including the super-admin, and retain access after password resets.
